A control system for an optical cell (light valve) is provided which comprises a first (oscillator) circuit supplied by a low voltage power source and including a primary winding of an induction coil and a secondary (resonant) circuit which includes the optical cell and a secondary winding of the induction coil. The secondary circuit includes the inductance of the secondary winding and the optical cell, and the induction coil provides a weak coupling between the primary and secondary windings. The resonant circuit provides a large over-voltage coefficient and great stability and the configuration made possible by the invention facilitates a significant reduction in the bulk of the control system.
Un système de commande de cellule optique (modulateur de lumière) comprend un premier circuit (oscillateur) alimenté par une source de courant basse tension et renfermant un enroulement primaire d'une bobine d'induction et un circuit (résonant) secondaire qui renferme la cellule optique et un enroulement secondaire de la bobine d'induction. Le circuit secondaire comprend l'inductance de l'enroulement secondaire et la cellule optique, et la bobine d'induction crée un couplage lâche entre les enroulements primaire et secondaire. Le circuit résonant a un fort coefficient de surtension ainsi qu'une grande stabilité, et sa configuration, selon l'invention, facilite une réduction importante du volume d'encombrement du système de commande.
